RFCONSULT UK is the personal website of Peter King, a retired RF engineer and radio amateur (M0LNB) based in London, UK. After 35 years working in RF, mobile and satellite communications, I now use this site to share some of my hobbies, projects and free tools. You’ll find amateur radio, eme, satellite, radio astronomy, astrophotography, technical notes, and a collection of free browser-based apps.

The apps cover RF links, circuits, systems, radio propagation, and specialist tools for satellite tracking and space. Ctrl-F5 to refresh.
